Enclosure:
(1) Cleaning Areas Checklist
Purpose:
This standard operating procedure (SOP) provides recommended actions for the enhanced
cleaning and disinfection of rooms or areas in facilities where suspected or confirmed COVID-
19 persons have visited. It is aimed at limiting the survival of novel coronavirus in key
environments. These recommendations will be updated if additional information becomes
available.
These guidelines are focused on community, non-healthcare facilities (e.g., schools,
institutions of higher education, offices, daycare centers, businesses, community centers).
Reference (e) provides guidance on the cleaning and disinfection of rooms of persons under
quarantine as well as associated worker protection practices according to expected job tasks.
Personal Protective Equipment (PPE):
Cleaning staff should wear the following items for all cleaning/disinfecting tasks, which should
be compatible with the disinfectant product(s) being used:
Disposable (latex/nitrile) gloves
Cleaning gowns or coveralls
Eye protection/Light goggles
As annotated in reference (f), the Centers for Disease Control and Prevention (CDC)
recommends wearing cloth face coverings in public settings where other social distancing
measures are difficult to maintain, especially in areas of significant community-based
transmission. Military personnel, DoD civilian employees, their family members, and DoD
contractors are strongly encouraged to follow CDC guidelines on the use of cloth facecoverings in public settings or where other social distancing measures are difficult to
maintain. When utilizing disinfectants, ALWAYS follow manufacture’s guidance for
respiratory protection.
Cleaning/Disinfection Materials
Industrial soap and water in spray bottles for cleaning surfaces prior to
disinfection
Heavy Duty Paper Towels
Large garbage bags with ties (for containment/disposal of used cleaning
materials)
Products listed on the following EPA-registered and approved list for effective
disinfection of surfaces exposed to coronavirus should be used.

cov-2
Per Occupational Safety and Health Administration (OSHA) Hazard Communication
standards (29 CFR 1910.1200), training should be provided to all cleaning staff on site prior
to performing cleaning tasks. Training should include when to use PPE, what PPE is
necessary, how to properly don (put on), use, and doff (take off) PPE, and how to properly
dispose of PPE. Workers should also be trained/informed on the hazards of the cleaning
chemicals used in the workplace.
Procedure per CDC and BUMED references (a)-(b):
1. CLOSE off all areas used by the ill persons and wait as long as possible before beginning
cleaning and disinfection to minimize potential for exposure to respiratory droplets (at
least 24 hours; but recommend 4 days - max virus life on surfaces).
2. Open outside doors and windows to increase air circulation the area (all rooms, where
possible) for at least 24 hours.
3. Cleaning staff should wear disposable gloves and gowns for all tasks in the cleaning
process, including handling trash.
4. CLEAN surfaces first.
If surfaces are dirty, Clean using a detergent or soap and water (and paper
towels/sponges) prior to disinfection.
5. DISINFECT cleaned surfaces.
For disinfection, diluted household bleach solutions, alcohol solutions with at least
70% alcohol, and most common EPA-registered household disinfectants should be
effective.
Diluted household bleach solutions can be used if appropriate for the surface.
Follow manufacturer’s instructions for application and proper ventilation. Check to
ensure the product is not past its expiration date. Never mix household bleach withammonia or any other cleanser. Unexpired household bleach will be effective
against coronaviruses when properly diluted.
Prepare a bleach solution by mixing:
5 tablespoons (1/3rd cup) bleach per gallon of water or
4 teaspoons bleach per quart of water
Products with EPA-approved emerging viral pathogens claims are expected to
be effective against COVID-19 based on data for harder to kill viruses. Follow the
manufacturer’s instructions for all cleaning and disinfection products (e.g.,
concentration, application method and contact time, etc.). Ensure adequate
contact time for effective disinfection (1-3 minutes, or as directed.)
For soft (porous) surfaces such as carpeted floor, rugs, and drapes, remove visible
contamination if present and clean with appropriate cleaners indicated for use on
these surfaces. After cleaning: If the items can be laundered, launder in
accordance with the manufacturer’s instructions using the warmest appropriate
water setting for the items and then dry items completely. Otherwise, use products
with the EPA-approved emerging viral pathogens claims that are suitable for
porous surfaces.
Adhere to any safety precautions or other label recommendations as directed (e.g.,
allowing adequate ventilation in confined areas, proper disposal of unused product
or used containers and donning appropriate PPE).
6. Avoid using product application methods that cause splashing or generate aerosols.
7. Cleaning/disinfecting activities should be supervised and inspected periodically to ensure
correct procedures are followed.
8. Cleaning staff should immediately report breaches in PPE (e.g., tear in gloves) or any
potential exposures to their supervisor.
9. Clean and disinfect all frequently touched surfaces in affected areas (e.g., counters,
tabletops, doorknobs, light switches, bathroom fixtures, toilets, phones, keyboards,
tablets, remotes and bedside tables) according to instructions described for products with
EPA-approved emerging viral pathogens claims.
10. Remove gloves and gowns carefully to avoid contamination of the wearer and the
surrounding area. Gloves should be removed after cleaning a room or area occupied by
ill persons. New gloves and gowns should be used for each day of cleaning/disinfecting.
11. Clean goggles with soap and water at the end of each day of cleaning/disinfecting.
12. It is recommended to close off areas used by the ill persons and wait as long as practical
before beginning cleaning and disinfection to minimize potential for exposure to
respiratory droplets. Open outside doors and windows to increase air circulation in the
area. If possible, wait up to 24 hours before beginning cleaning and disinfection.13. When cleaning is completed, Collect soiled materials and PPE in a sturdy, leak-proof
(e.g., plastic) bag that is tied shut and not reopened. This waste can go to the regular
solid waste stream (e.g., municipal trash) as it is not biohazardous or regulated medical
waste.
14. After cleaning, removal, and disposal of PPE, immediately Perform hand hygiene. Soap
and water should be used if the hands are visibly soiled.
Cleaning staff should clean hands often, by washing hands with soap and
water for 20 seconds. If soap and water are not available and hands are not
visibly dirty, an alcohol-based hand sanitizer that contains 60%-95% alcohol
may be used. However, if hands are visibly dirty, always wash hands with soap
and water.
15. Per ref (a), if it has been more than 7 days since the person with suspected/confirmed
COVID-19 visited or used the facility, additional cleaning and disinfection is not
necessary.
Notes:
No additional cleaning is needed for supply and return ventilation registers or
filtration systems for the building.
No additional treatment of wastewater is needed before discharging to sanitary
sewer.Enclosure (1)
